This photoelectric detector detects the smoke by a couple of infrared diodes. The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber. The chamber can shield external light, but don't affect the smoke into it. While have no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive the more and more light, when the smoke attains the certain density, the detector can give out alarm signal. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal. The detector adopts the special structure design and ASIC, has the dustproof, mothproof and anti outside light interference feature, etc. The detector is suitable for detect the smoke in house, shop, hotel, restaurant, office building, school, bank, library, computer house and storehouse, etc.
Features:
Built-in high accurate infrared photoelectric sensor to detect smoke or combustion particles in air, rather than sense heat, flame or gas.
If it detects smoke and the smoke attains the certain density, it will make a sound over 85dB and the red LED light will be flashing.
Suitable for all the places, such as office, hotel, kitchen, bedroom, bathroom, garage, bank, library, computer house, storehouse, etc.
When the voltage of battery is low or the chamber is dirty, it will beep once per 40s to remind you.
With test function and auto reset function.
High Stability, it has the dustproof, mothproof and anti outside light interference feature.
Powered by a 9V battery (not included), comes with 2 screws and 2 plastic inserts, easy to install.
